You first have to make a choice, which medium you are going to use.... CD or Vinyl ?
Nowadays I should go for CD right away. When I started playing there weren't decent CD players so I started on vinyl and later made the switch to CD. If I should be choosing again with the CDJ's that are available now, I would directly start on CD.You go for vinyl ??
The reference deck is the Technics SL-1200/1210 MK2
, all decks are compared to that. In some cultures Vestax might be named as the leading brand (mainly hiphop dj's). At this moment there are some EOM turntables
from brands like Reloop, Stanton, Akyama etc that all produce this one model turntable featuring direct drive, high torqua, wide pitch range and some other features.
There are long threads allready trying to decide which turntable is the best, but not 1 model is the best, but Technics is a true DJ icon. If you should go for vinyl, I would go for the SL-1200.Go for CD ??
Then again : make a choice : Rotating- or non-rotating
In general, the better the Jog performance, the higher the price of the deck. When you want a rotating Jog dial on your CD player, you might want to look at : Numark CDX
or Denon DN-S3500.
To my opinion, the best CD player with a non-rotating Jog is the CDJ-1000
MK3, better for your wallet is the CDJ-800
MK2. Both are no cheap players, but they offer a decent quality.
If you let go of the demand for scratching your choices are the easiest. There are lots of decks available from lots of different brands.... My favourite would be CDJ-200
Hope this helps a little to make your choice of what to do next
